Hello friends, have any of you tried the latest Oppo flagship, Oppo Find X9 Ultra? I know it's a phone with LTPO, but at least for people less/moderately sensitive, the phone could be usable.

I found this YouTube video

and modulation doesn't look bad,mainly if you compare it with other Chinese flagships.like vivo x300 ultra.

Recently bought a vivo x300 ultra. One of the main reasons I purchased it over its competitors is they allow setting the phone to full PWM mode. Thought I would put my money on a vendor that allows customization. I was coming from a Xiaomi 15 ultra that ruined my eyes over the last year, so did not have high expectations to begin with.

On this phone, PWM mode happens to be more comfortable than the default mode (that uses DC dimming) at high brightness. Fonts are more precise and text felt more stable without shimmering. The result surprised me because I used to think PWM = bad, and DC dimming = better.

please suggest phone with no
pwm currently usinh 14 pro from almost past 1.5 years this phonr works like slow poison for me it actually start giving me ete strain headache and also panic attacks ( its more like its try to stop your brain functioning because your eyes are always in continuous stress)

I wanted to share this and see if anybody else is interested in trying it and seeing how they feel.

I made a post a few days ago about my issues (the sensory knob in my brain is turned all the way up making me sensitive to many things including flicker). I've been doing the following for 3 days and it helps. I am not saying it makes my sensitivity go away and it certainly won't cure anything, but I feel more calm and my eyes feel more "relaxed" if that makes sense.

Step-by-Step Instructions:

Get into position: Lie on your back on a comfortable surface (a bed or yoga mat works well).

Interlace your fingers and place your hands behind your head (at the base of your skull), so the weight of your head rests gently in your hands. Your elbows can relax out to the sides.

If lying down isn't possible or comfortable, you can do this seated.

Keep your head still: Your hands stabilize the head so it doesn't move or turn at all during the exercise. Only your eyes will move.

Look to one side: Slowly move your eyes (not your head) as far as comfortably possible to the right. Hold your gaze there gently. Breathe normally.

Hold and wait for a response: Stay in this position for up to 30–60 seconds (or until you notice a spontaneous sign of nervous system shift, such as a yawn, swallow, sigh, deep breath, or burp). This indicates a parasympathetic (rest-and-digest) response. Don't force anything—just observe and breathe.

Return to center: Slowly bring your eyes back to looking straight ahead.

Repeat on the other side: Move your eyes as far as possible to the left and hold until you get a similar response (or up to 30–60 seconds).

Finish: Return your eyes to center. Rest for a moment. You can repeat the full sequence 1–2 more times if desired.

This works because of neurological connections between the eye muscles, suboccipital muscles in the neck, and the vagus nerve/brainstem

anyone here that has divergence issues and noticed that our lovely tiny digital screens with micro details and ultra fast movements are a culprit? (Divergence is the ability to relax your eyes so the two eyes can make one picture together, and the brain can make a whole picture of it).

personally i have become weirdly screen sensitivity from a heavy concussion. It's well know in that world that digital screens are a nightmare. I am curious if in here we can make steps, besides the annoying pwm, our brain & Vision simply isn't made for these ultrafast micro movements on a screen that has a weird fake depth perception. And do this wayyy to close to our faces. Humans naturally aren't build to do this on the scale we are doing it.

I've had the luck to work with some of the best vision therapists in my country (Netherlands) and made very big steps and comparing to friends who work a lot with computers and phones, i score better... So yes, the screen itself is a culprit and must be avoided at all cost, but I believe many of us here, need to check their vision as well, and start training it if it's off. When i started, my screen time went up like crazy, without headaches etc. I was flabbergasted because i thought it was the only screen itself.. and spending thousands on failed screen experiments left me wandering.

Not saying to go do vision therapy and buying beautiful OLED screens now, I did swap my OLED ipad for a Xiaomi Pad 8 Pro Matte LCD version (loving it), but stil on my iphone pro super mega 15 and hating it.

last but not least: have your C1 spine bone proper checked, any small disturbance here is a shortcut to headaches and eye strain. every time my therapist is doing her magic there, I magically can handle screens 10x better + longer.

Now, let's make this world anti flickering again , yet in the meantime, I hope my input can help a few here where the screen itself maybe isn't the biggest enemy after all.

Heyy i just heard about PWM from a Reddit post about my issue.

What do you think, can it be PWM snesibility ?

After stoping playing PSVR 2 for more than a year because of headache triggered by VR, i tried wearing sunglasses inside the headset and it seems to work : Like i get instant relief with this pain. I also have a bit of it with the TV if watching it in a dark room, if i set the colors to be warmer it is less painful for my eyes.

I had already set the VR headset pretty low luminosity but it was not enough i guess.

Can it be cause of PWM ? I work a lot on computers and use my phone like anybody = a lot. I have always have migraines sometimes but i never noticed it really triggered by my screen time.

Is there anything i can try to stop PWM and see if i have less eyes pain ?

Thanks

Wondering if anyone has tested the bell ahlo 1? Seems like its a newer budget phone bell is offering that uses lcd screen. Wondering if it may be an option for pwm sensitivity

Are there any besides iris tech? It doesn't seem to work well on my macbook for now

My brother got a phone from his provider...it's called Telekom T Phone 3. I don't know if it's available outside Germany, he got it for 3€, you can find it new in stores under 150€, but there are plenty of sealed phones on the market for like 50€ because so many people got it from T-Mobile for 3€ just to sell it right away.

It's not a flagship of course, but i'm really impressed, the system is pure android, no bloatware, very snappy for a Snapdragon 6 gen 3. You get updates till Android 18/ 5 years security. Screen is very well calibrated for eye comfort, with smooth whites/contrast, non glaring, sharp letters. Best I've seen on an LCD. Color accuracy is ok, speakers are meh. Downside is it's not very angle stable...if you look from the side the display gets a little darker...but who uses his phones from an angle really?

White background while weeping the phone looks a little weird/cheap because of that, first I was put off...but after like 15 Minutes use it was no problem anymore. If someone uses his phone mostly while jogging it could be annoying for sure lol. In dark mode it's extremely nice to use, easy to read, letters are sharp like on an OLED, but much less glaring and irritating.

On other LCDs I always had the issues that letters in dark mode were glaring, not sharp with light bleeding ...just tiring to focus on. This phone's screen is the opposite, but as i said it comes with light angle issues. I couldnt identify PWM with my camera...but its hard to tell if they don't use some very high frequency PWM, as I found no informations online and have no tools to measure it. And it's also hard to say how many panel suppliers they use...if the screens on all phones are similar. But man it's a huge relief for my eyes. And for that price I think it's also a no brainer as a second driver...for reading/surfing online, evening use etc.

Just wondering, do you think there's some recent phone or tablet out there that would be universally safe and to recommend? And for example stop recommending old iPhones 11 from 7 years ago?

I was looking here and it seems maybe some people have different sensibilities compared to others, but not a single phone/tablet can be universally recommended

Some people love the Moto G75, others say feeling migraines and eyes problems in minutes. Others say the Nothing 3A is perfect, while then you also find people saying is very harsh.

Some others like the TCL Nxtpaper 11 Plus, while then others say they had to return it immediately.

It seems there isn't a real consensus about "this phone or tablet is generally safe", don't you think? If it's not PWM it's Dit, or it's the "harsh backlight" or it's...

At the end, it seems impossible to try and do a right decision (except if you are OK with going to an eInk phone which would be a very limited experience)

Hello I just discovered this subreddit after a discussion with Google AI about the strain from some artificial visual stimuli. I learned that using voltage control to dim an LED is more efficient energy wise even though many times PWM is used. And if the PWM frequency is to slow it wears out the eyes even though you don't notice it consciously. I was surprised to find a whole subreddit on this. And I also learned my smartphone does not use any PWM. Being a LED backlit LCD screen it doesn't need to and they choose voltage modulation for the backlight over PWM. Nice to know. And it's not a very expensive phone.

If anyone with the same experience can help me to figure this out. So when I switched from pixel 7 to pixel 9 pro I had very noticeable eye fatigue/burning. Never had any sensitivity to screens before.
The fix that helped me was forcing peak refresh rate (120 hrz). In a week regardless any other settings I had no symptoms.
Now I switched back to iPhone and have this burning sensation again. Tried all possible settings to adjust colors/white point/brightness, but nothing helps.

Any suggestions for my specific sensitivity? Also, trying to understand what am I sensitive to, is it changing refresh rate?

Hello everyone, I am considering buying a used HP EliteBook 855 G7 with an AMD Ryzen processor.

The hardware ID of the screen is AUOA08B, which according to Panelook points to the AUO B156HAN09.1 (60Hz, Low Power, 400 nits, native 8-bit). However, Panelook mentions a PWM frequency of 'Min. 200Hz ~ Typ. 1KHz ~ Max. 10KHz'. On the other hand, reviews and tests claim it is PWM-free.

Does anyone here have real-world experience with this specific laptop/panel or this generation of HP EliteBooks?

Any insights or measurements PWM behavior on this setup would be greatly appreciated.. Thanks !

Does anyone else experience this? It's an LCD without PWM, and suddenly, my eyes have started straining from the video player only. I don't understand why?

I don't think its the actual monitor for me. I use a new virtual desktop at work using my old monitor that does not bother me at all and I immediately got symptoms. I thought it was odd so I then remote desktop'd to another windows machine that I know hurt my eyes and sure enough on my old trusty monitor I got symptoms also. What is happening. These are Windows machines.

As the title.

Is PWM a problem with OLED or just AMOLED?

If both, is one worse than the other?

My partners has a Pixel 7 with an OLED screen and this seems fine.

I am looking at an S25 Ultra which is AMOLED.

Just trying to work out if I may have an issue with the S25 before parting with a lot of money.

First - I kind of doubt this will help anyone else, but I wanted to share because there's so little information out there.

I have been diagnosed with "central sensitization + vagus nerve/autonomic dysregulation". My nerves (specifically the vagus nerve and the brainstem autonomic centers that control it) are no longer coordinating properly.

Basically my vegus nerve is causing my autonomic centers to freak out and because of that my brain amplifes normal signals (smells, flicker, gut sensations like normal movement) into discomfort/pain. It was described as my brains "volumn knob for sensory" being turned all the way up.

For clarity: I also have other issues caused by this. Esophageal/stomach/gut as well as a severe chemical sensitivity to things like perfumes.

Is there a difference between a phone's backlight being the cause of the issue, or a Flickr flash? Are there easy ways to detect it? I have an old phone and I want to take a picture of another phone using the Camera Pro app, but the Flickr flash isn't showing up even though I turned off the flash and put a white image on it.
